What do you mean by "national hospital" - do you mean US government?
NIH has free trials of the F18 DCFBC:
/clinicaltrials.gov/ct2/show/NCT02190279Closer to you, there's a clinical trial of FACBC in Jacksonville FL:
/clinicaltrials.gov/ct2/show/NCT02680041On the east coast..
I think there will be a new trial of F18 DCFPyL at Johns Hopkins starting soon. Contact Steve Y. Cho.
Memorial Sloan Kettering is testing a good one:
/clinicaltrials.gov/ct2/show/NCT02559115There are more on the west coast at UCSF, Stanford & USC. Also, some places may be selling them outside of clinical trials. You can check if Sylvester offers any.
